Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
SeeShifting Into Park 0168 and
Engine Exhaust 0170.
Dual Clutch
Transmission
This vehicle is equipped with a dual
clutch transmission that contains an
integrated rear differential. The dual
clutch transmission provides an
extremely connected feel due to the
direct connection between the
engine and gear box. This
arrangement provides very fast shift
times for maximum performance.
Automatic driving mode is selected
by pulling D on the transmission
range selection panel and provides
fully automatic shifting operation which can be further refined using
driver mode control. Upshifts may
be delayed regardless of mode
selection or ambient temperature
until the engine is warmed up.
Manual operation can also be
selected. See Manual Mode later in
this section.
This transmission is electronically
controlled. The shift switches are on
the center console. The selected
gear position will illuminate red on
the shift switch, while all others will
display in white. The indicator on
the shift switch may flash if the shift
is not immediate or if the gear is not
fully engaged. This may occur in
very cold conditions or when Double
Paddle Declutch is used.
The transmission does not operate
when the vehicle is off.
If the vehicle is in ACC/
ACCESSORY, the transmission can
be shifted into P (Park).
If ENGINE START/STOP is pressed
twice while at a relatively high
speed, the engine will turn off and
the transmission will automatically

or the Head-Up Display (HUD),
if equipped. SeeHead-Up Display
(HUD) 0110.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear, when
available, will allow the vehicle to
gain more traction.
The Manual Paddle Shift system
can be deactivated by pulling the
D (Drive) switch on the center
console.
With the transmission in D (Drive),
pull the right + paddle or the left
− paddle to place the transmission
in Temporary Manual Paddle
Shift mode.
To exit Temporary Manual Paddle
Shift mode do one of the following:
. Hold the + paddle for more than
one second.
. Drive at a steady speed without
manual shifts or aggressive
cornering for more than
six seconds.
. Bring the vehicle to a stop. While the Manual Paddle Shift
feature is active, the transmission
will automatically downshift through
the gears as the vehicle slows. The
transmission will select 1 (First) gear
as the vehicle stops. From a stop,
the vehicle will start from and hold
1 (First) gear unless Manual Paddle
Shifts are used to shift into a
different gear, or D (Drive) is
selected.
To cause the transmission to
downshift to the lowest gear
possible for the vehicle speed, in
Manual Paddle Shift or Temporary
Manual Paddle Shift mode:
.
Pull and briefly hold the
−paddle. If the paddle continues
to be held as the vehicle slows,
downshifts will continue as
vehicle speed allows.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
vehicle speed is too fast or too slow,
nor will it allow a start from any gear
other than 1 (First) gear.
When in Manual Paddle Shift mode,
if upshifting does not occur when
needed, vehicle speed will be limited to protect the engine. When
in Temporary Manual Paddle Shift
mode, the transmission will
automatically upshift if the
accelerator pedal is pressed all the
way to the floor.
Manual Paddle Shift can be used
with cruise control. See
Cruise
Control 0196.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
To prevent damage to the
powertrain, Manual Paddle
downshifts to a lower gear cannot
be done above certain speeds.

Mode Description
uWeather :Weather Mode is used
for slippery surfaces to help control
wheel speed. This can compromise
the acceleration on dry asphalt.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the
Vehicle Is Stuck 0159. See “Driver
Mode Attributes,” later in this
section.
sTour : Use for normal city and
highway driving to provide a
smooth, soft ride. This setting
provides a balanced setting
between comfort and handling. This
is the standard mode. See “Driver
Mode Attributes,” later in this
section.
rSport : Use where road
conditions or personal preference
demand a more controlled
response. Used for spirited driving.
In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected. These features maintain lower
transmission gears to increase
available engine braking and
improve acceleration response. The
vehicle will exit this feature and
return to normal operation after a
short period when no spirited driving
is detected. See
“Driver Mode
Attributes,” later in this section.
tTrack :Track Mode is used for
closed race tracks. Use when
maximum vehicle handling is
desired.
When in Track Mode, the dual
clutch transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. See “Driver
Mode Attributes,” later in this
section.
qMy Mode : My Mode is used to
personalize everyday driving. This
mode is designed to allow the driver
to configure vehicle sub-systems to
their own preference for city or
normal driving.

While pressing the accelerator pedal
or shortly following the release to
override cruise control, briefly
pressing SET–will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you may have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
may have to brake or shift to a lower
gear to keep your speed down.
If the brake pedal is applied, cruise
control will disengage. Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive).
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.
If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver ’s gear selection is
active.
. If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper gear for the terrain or select D
(Drive) on the shifter for full
automatic transmission
operation.
Ending Cruise Control
. Step lightly on the brake pedal.
. Shift the transmission to
N (Neutral).
. Press
*.
. To turn off cruise control,

Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enough so the jumper cables can
reach, but be sure the vehicles
are not touching each other.
If they are, it could cause a
ground connection you do not
want. You would not be able to
start the vehicle, and the bad
grounding could damage the
electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brakes.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the
accessory power outlet. Turn
off the radio and all lamps that
are not needed. This will avoid
sparks and help save both
batteries. And it could save the
radio!
4. Open the hood. See Hood
0 21.
5. Release the four clips for the
left and right outer covers.
